STUFFING-BOX PACKING.

Specication of Letters Patent.-

Patented an. iid, 1913.

Application filed October 2B, 1911. Serial No. 656,278.

l To all whom it may concern Be it known that I, JAMES WALKER, a subject of the King of Great Britain, residing at Lion Works, Garford street, Poplar, E., London, England, engineer, have invented certain new and useful Improvements Relating to Stuliing-Box Packing, of Which the following is a specification.

This invention relates to packing for stuifing glands of the type in which the inner port-ion in contact with the rod is formed as a loose soft art or lip in such manner that it shall not be liable to deformation in'use.

According to the invention I provide such packing made from folds `of asbestos or other suitable cloth wound one around the other so that thus there is only 011e ed e oitv cloth eX osed, on the workinv face o theloose so part or lip at the edge thereof.

The invention is'illustrated in the accompanying drawing which illustrates the form of packing provlded according to the inven- The packing is advantageously'made of fabric a, the yarn of which is impregnated with a suitable compound prepared tol resist.- the actionv of water or steam. The vcloth woven from yarn thus pre ared is cut into suitable sha e, but instea of the packing being forme with a number of folded edges or strips of the fabric exposed, the `fabric is folded up one fold upon the other so that thus thereare no edges of the fabric exposed on the working face except that necessary in the formation of the lip b. The packing thus formed is pressed in a mold. In this way a very solid and durablelpacking is pro- Y vided and the loose soft part or lip is made suliciently thin to be sensitive to moderate pressures for which the 'packing is more especially suitable= y,

I prefer to provide 'the' packing from hemp or asbestos cloth' vforthe moderate pressure for Whichsuch a packing is more especially suited.

What I claim as my invent-ion and-desire v to secure by Letters Patent is i 1. Packing consisuiing of fabric which is rolledone'layer ar und the other so as t-o leave only one edge of the fabricexposed on the working face,vwhich rolled fabric is then folded to form a loose li and molded.

2. Packing consisting of abr'ic impregnated with a steam and water resisting substance which is rolled one layer around the other so as to leave only one edge of the fabric exposed on theworking face, which veo
